This change introduces a new EditorThemeManager class to abstract theme generatio and its subroutines. Logic related to EditorTheme, EditorColorMap, and editor icons has been extracted into their respective files with includes cleaned up. All related files have been moved to a separate folder to better scope them in the project. This includes relevant generated files as well.
